The use of large metal on metal bearings has led to a reduction in the risk of dislocation post hip arthroplasty. Because of this, and also because of the technical difficulties associated with resurfacing surgery in particular, it could be argued that a less meticulous approach to acetabular cup placement has developed in comparison with conventional metal on polyethylene arthroplasty. Resurfacing cups may produce significant clinical problems when placed at the extremes of version, including increased production of metal debris and psoas tendonitis. Presented in this article is evidence that EBRA software (Einzel-Bild-Roentgen-Analysis, University of Innsbruck, Austria) can be used to reliably assess the version of resurfacing cups, when radiographs are of sufficient quality. The cups have characteristic appearances when placed at the extremes of version. These characteristics can allow the surgeon to identify poorly positioned cups without the use of software.
